Clean up the array_size.cocci warnings under tools/testing/selftests/bpf/:
Use `ARRAY_SIZE(arr)` instead of forms like `sizeof(arr)/sizeof(arr[0])`.
tools/testing/selftests/bpf/test_cgroup_storage.c uses ARRAY_SIZE() defined
in tools/include/linux/kernel.h (sys/sysinfo.h -> linux/kernel.h), while
others use ARRAY_SIZE() in bpf_util.h.

Remove the second part of prog loading testing helper re-definition:
-Dbpf_load_program=bpf_test_load_program
This completes the clean up of deprecated libbpf program loading APIs.

The cgroup selftests did not declare the bpf_log_buf variable as static, leading
to a linker error with GCC 10 (which defaults to -fno-common). Fix this by
adding the missing static declarations.

Convert test_cgroup_attach to prog_tests.
This change does a lot of things but in many cases it's pretty expensive
to separate them, so they go in one commit. Nevertheless the logic is
ketp as is and changes made are just moving things around, simplifying
them (w/o changing the meaning of the tests) and making prog_tests
compatible:
* split the 3 tests in the file into 3 separate files in prog_tests/;
* rename the test functions to test_<file_base_name>;
* remove unused includes, constants, variables and functions from every
test;
* replace `if`-s with or `if (CHECK())` where additional context should
be logged and with `if (CHECK_FAIL())` where line number is enough;
* switch from `log_err()` to logging via `CHECK()`;
* replace `assert`-s with `CHECK_FAIL()` to avoid crashing the whole
test_progs if one assertion fails;
* replace cgroup_helpers with test__join_cgroup() in
cgroup_attach_override only, other tests need more fine-grained
control for cgroup creation/deletion so cgroup_helpers are still used
there;
* simplify cgroup_attach_autodetach by switching to easiest possible
program since this test doesn't really need such a complicated program
as cgroup_attach_multi does;
* remove test_cgroup_attach.c itself.
